LED CBI 5MM YELLOW THROUGH HOLE 5338H7

Part Overview

The 5338H7 is a circuit board indicator LED manufactured by Visual Communications Company (VCC) in the 5338H series. This component is a single yellow LED with a 5mm round domed top lens, designed for through-hole mounting applications. The part is classified as obsolete, necessitating identification of equivalent substitute components for ongoing design requirements and procurement needs. The 5338H7 operates at 2.1V with a 60mA current rating and delivers 10mcd luminous intensity at a peak wavelength of 585nm.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 5338H7 is determined by alignment of the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Color: Yellow (585nm peak wavelength)
• Voltage Rating: 2.1V nominal operation
• Configuration: Single LED element
• Compliance: ROHS3 and EAR99 classification

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole configuration
• Lens Size: 5mm form factor
• Package Type: Bulk or standard packaging

The substitute part 5500307F from Dialight meets these core substitution criteria. While the 5500307F operates at a lower current rating (20mA versus 60mA) and features a right-angle mounting option with diffused lens characteristics, it maintains electrical compatibility through identical voltage rating, color specification, and wavelength. The difference in current rating and lens configuration represents a design trade-off that must be evaluated within the specific application context.

Parameter Comparison

Engineering Selection Recommendations

The 5500307F from Dialight is an active production substitute for the obsolete 5338H7. Both components maintain ROHS3 compliance and EAR99 export classification, ensuring regulatory continuity in applications requiring these certifications.

Key Considerations for Selection:

The 5500307F operates at 20mA maximum current compared to the 5338H7 specification of 60mA. Circuit designs must accommodate this reduced current capacity through appropriate series resistor adjustment. The 5500307F delivers 12.3mcd luminous intensity, which exceeds the 5338H7 output of 10mcd, providing improved visibility despite lower current consumption.

The 5500307F offers right-angle mounting capability in addition to standard through-hole orientation, providing additional layout flexibility. The diffused lens type of the 5500307F differs from the clear/tinted lens of the 5338H7, affecting light distribution characteristics and viewing angle (60° specified for the 5500307F).

Both components share identical 2.1V voltage rating and 585nm yellow wavelength specification, confirming fundamental electrical compatibility. MSL rating of 1 (Unlimited) for both parts indicates equivalent moisture handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5500307F directly replace the 5338H7 without circuit modification?

A: Direct replacement requires circuit evaluation. The 5500307F current rating of 20mA is lower than the 5338H7 specification of 60mA. Series resistor values must be recalculated to accommodate the reduced current capacity while maintaining proper LED operation at 2.1V.

Q: What is the impact of the diffused lens on optical performance?

A: The 5500307F features a diffused lens compared to the clear/tinted lens of the 5338H7. Diffused lenses scatter light over a wider viewing angle (60° for the 5500307F) but reduce peak intensity in the direct viewing direction. Application requirements for light distribution must be evaluated.

Q: Are there mounting orientation differences between these parts?

A: The 5338H7 is specified for standard through-hole mounting. The 5500307F supports both standard through-hole and right-angle mounting configurations, providing additional design flexibility for PCB layout constraints.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 5338H7 and 5500307F are ROHS3 compliant and classified as EAR99 for export purposes. MSL rating of 1 (Unlimited) applies to both components, indicating equivalent moisture sensitivity handling.

Q: What is the luminous intensity difference between these parts?

A: The 5500307F delivers 12.3mcd compared to the 5338H7 output of 10mcd. Despite lower current consumption, the 5500307F provides approximately 23% higher luminous intensity, resulting in improved brightness for indicator applications.

Q: Is the 5500307F available in active production?

A: Yes. The 5500307F is classified as active production status, ensuring ongoing availability and supply continuity. The 5338H7 is obsolete and no longer manufactured.
